guys,
I made this program and I would like to have your opinion and suggestions if this is correct; I having trouble with malloc (), the objective here is I need to allocate enough memory for the variable newstring after it was concatenated using strcat function and I have no idea how to check if my malloc() was allocated the space for the variable newstring.
Appreciate your positive response.Code:/* This will use malloc() function to allocate */
/* memory for the concatenated two strings */
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char *conca_str(char *, char *);
int main( void )
{
char *str1 = "Hello";
char *str2 = " World!";
char *join;
join = conca_str(str1, str2);
printf("%s\n", join);
free(join);
return 0;
}
char *conca_str(char *string1, char *string2)
{
char *conca, *newstring;
newstring = strcat(string1, string2);
conca = (char *) malloc (100);
conca = newstring;
return conca;
}
